mrsovsn ENAMELLED WATER-COOLERS.

Be it known that 1,0HARLES O. SAVERY, oi the city of Philadelphia, in the county of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Water-Coolers and Refrigerators;

and I, do hereby declare that the followi'ng'is a full and exact description thereof, reference being bad to the accompanying drawings, making a part of this specification, in'which- Figure 1 is an elevation view of my apparatus.

Figure 2, a sectional elevation of tlie same.

The nature of my invention consists ina peculiar mode of construction for Water-coolers and refrigerators, such, that whatever is stored in the provision-chamber will no longer be apt to be spoiled or deteriorated by the dripping of rusty or dirty water, which will condense on the bottom of' the water and ice-tank of such apparatus. I v p To enable others'skilled in the art to make and use my invention, I will now proceed to describe its construetion and operation. I

A is the body or outside of my cooler. A is made of metal,' of any suitable kind.

B is the bottom-plate of the apparatus, A fitting on B in the usual way.

A'and B to be made and shaped or ornamented as may be desired. 7

Inside of Ais placed ametallic cylinder, ,0 M, its bottom, B, being at the distance of three-quartersof an inch, or about, of bottom, B. Thediameter of (3' M is smaller than that of A, so as to allowa space between A and C M of half an inch or so. The height ot'O M to be about one-third of the height of the whole apparatus.

The top of cylinder 0 M is open, so as to receive a cylindrical casing, G Z, secured there by means of sol timing, or any other water and air-tight joint, at a I). 4 v v The height of 0 Z is about that of G M, and said casing 0 Z is opened, and receives a conical metallic vessel, 0 Its bottom is on a levclwith the top of cylinder 0 M, and its (C V) top on a. level with the top of A. I

The opening between top of A and top of C V is closed by a metallic covering, 0 R, and C V is itself closed by means of lid L D. v

A small metallic tube, M T, starts :from the top of O M, and reaches the under face of G R, where it is secured. C M is opened at both ends, and a small hole drilled through 0 R permits chamber 0 H to discharge any vitiated air throughsaidpipe M T. s I

The portion of the outer surface of 0 V from K to K is ,enamelled outside and inside, for the purpose hereinafter shown.

l I The whole space, S P, S P, SI, 5 1 860., is filled with any non-conductor matter, and a spigot or spout, 'S Q, is set into body A, so as to reach C V, which can be discharged through said spigot.

Lastly, a small discharge-tube, D S, is set under bottom of O M, as discharge-spout of said chamber.

I reserve the right to construct my'said and above-described apparatus of any suitable metals,- such as cast, or sheet, or wrought iron,"brass, or copper sheet, 'zinc, tin, 850., 3m, to give it any ornamental shape I may please;

-- Thus constructed, my apparatus is now readyfor use.

I place the ice and water in vessel 0 V, and closing the lid L D, which'is itself stufl'ed with non-conductor.

packing, the-iceand ice water will thus be entirely insulatedfrom the outsideair, and therefore will keep very cold all the time.

' I The said ,ice-water being drawn at spigot S Q, through door D R of chamber 0 H, I have access to, the interior of said chamber, where I'can storeanything like butter, milk, meat, or any eatables, of any description I may desire to keep over-night'or in warm Weather. I l

The object of enamelling the ice and water-tank is as follows:

.First. Inside: it is to prevent the water from acquiring any metallic taste from the tank it is contained in Second. Outside: water will always condense. on the outside of a vessel containing ice or cold water. The vessel being metallic, will, after awhile, become rusty, and the water condensed on its outside will therefore be no longer pure or clean. Its'drippings will consequently spoil the eatables underneath. But if the outside of the vessel is enamelled, the water condensing there will remain clean find pure, and its drippings will no longer spoil the provisions in the provision-chamber.

This explains why I have mentioned enamelling the inside of water and ice-tank O v, and its outside, from v K to K, and its bottomelso.

Many'water-eoolers and refrigerators have eontrivances and tubes to bring cold air, either from the outside or the ice o rT'hter-tank, to .the provision-chamber, but none to carry out the air from said chomber, vitiated by the emanations of the difi'erent kind of things stored there. Such is. the object of vitiated-air tube M T, above described, and one of the most important points of my construction. p

I do not claim having invented or being the originator of the apparatus used as water-cooler and refrigerator; the principle is known already. And although the construction presented in the above description is novel, in its simplieityand effectiveness, I do not lay claim to it; but having thu'sdescribed my invention,

What I claim, and desire to secure by Letters Patent of the United States, is p 1. The mode of enamelling the inside and outside of the water and ice-tank (or both, if used separately) of a water-cooler and refrigerator, in the manner and for tllPlllPOSG above set forth and described.

2. The combination of a water and ice-tank or water and ice-tanks, enamelled inside and outside, with a water-cooler and refrigeratom for the purpose and in the manner above set forth. and described.

3. The combination of vitiated-air discharge-tube or pipe M with the provision-chamber of a water-cooler and refrigerator, in the manner and for the purpose above set forth and described.
